Another New Corded Impact Wrench for Hitachi, the WR22SA Offers Class Leading Tightening Torque
NORCROSS, GA., September 22, 2005 - Hitachi Power Tools today announced its new 3/4" Impact Wrench, the WR22SA that produces a class leading torque of 450 ft/lbs and features Hitachi's patented IDI (Internal Double Insulation) technology which significantly increases tool life and durability. Designed for the serious professional, the WR22SA offers the ultimate in power to accomplish the most demanding fastening applications with comfort and ease.
With its powerful 7.5 Amp, 850 Watt motor, the WR22SA offers class-leading torque, which ultimately saves time and energy. It generates 1,800 RPM and an impact rate of 2,000 IPM making it more than capable to overcome stubborn fasteners and get the job done. The wrench is ideal for tightening and loosening nuts and bolts in the automobile, ship building, agricultural and construction industry. It is also useful when assembling scaffolding, installing electrical equipment, plumbing, HVAC installation and other various fastening applications.
The armature bearing on the WR22SA is seated in aluminum, not plastic, to withstand the high heat and stress resulting from extreme use. It is constructed using Hitachi's patented IDI technology that enables the aluminum housing to be intertwined with an injection molded inner nylon core. This technology combines the durability of an all metal body tool with the double insulation advantages of today's tools with plastic housings, which improves tool reliability, safety and greatly extends tool life.
The WR22SA corded impact wrench is covered in a soft, yet durable elastomer compound, which absorbs vibration. This coating also provides a comfortable and slip-resistant grip and prevents the tool from sliding off a surface when not in use. The handle is angled outward in order to ergonomically conform to the user's hand. The large nose bumper protects the tool's gear cover and additionally protects the user from heat if touched during continuous operation. A large forward/reverse rocker switch is designed for convenience to quickly change the fastening direction. At only 11 lbs and 12-5/8" in length, the WR22SA is the lightest and most compact impact wrench in its class, reducing end user fatigue and allowing for flexible maneuvering in tight situations.
This 3/4" impact wrench reflects the ergonomic "Inspire Design" being implemented by Hitachi Power Tools. Hitachi is pioneering yet another new trend in the industry- tools that incorporate the latest technology with ergonomic design- a look that will modernize the traditional shop or jobsite.
